A key playmaker on the high-powered Oklahoma offense was carted off with an injury in the fourth quarter of the Big 12 championship on Saturday

Marquise “Hollywood” Brown suffered a lower-leg injury in the fourth quarter, and returned to the sidelines with a boot on his left leg. Brown has until Dec. 29 to rehab and heal the injury before the Sooners play Alabama.

In an interview with ESPN on Sunday, coach Lincoln Riley offered an update. The junior underwent some preliminary tests on Saturday and then some more Sunday morning.

“Going to meet with the doctors in the next couple of days and see where we’re at,” Riley said. “It was certainly a significant enough injury that there was no way he was going to be able to return in the game. The extent of that is a little bit unknown. But we’ve got a great medical team and we’ll fight hard to try and get him back.”
